Thanks for pointing out that concierge category is different. Do you know if Sky still price less than Disney Concierge?Keep in mind that Disney Concierge is not equivalent to Celebrity Concierge; it would be more equivalent to their suites (starting at Sky Suite level).
We've been sailing in Celebrity suites and really enjoy them. Suites get a butler, a private restaurant, a private lounge, and lots of perks. Usually suites can book with four perks included: premium beverage package, free wifi, free gratuities, and free OBC.
